One of the Hasidic heirs in the holy war for leadership of the Satmar sect is moving to Brooklyn to stake his claim.

Rabbi Aaron Teitelbaum is leaving the Hasidic enclave of Kiryas Joel in Orange County after 23 years for Williamsburg, where his younger brother, Rabbi Zalman Teitelbaum, has been recognized as leader of that congregation.

Other congregations around the world backed Aaron yesterday as the successor to Grand Rabbi Moses Teitelbaum – but supporters of Zalman emphasized their father had named the younger brother in his will, which was read after his death on Monday.

Aaron was expected to arrive last night at his Williamsburg residence and begin sitting shiva – the Jewish period of mourning – just blocks away from where Zalman was doing the same in the home of their father.

Aaron will remain in Williamsburg at least until Monday and later establish his primary residence in the area, supporters said.

Asked to explain the move, one prominent supporter said, “It’s the Satmar headquarters.”

Zalman’s supporters said Aaron was welcome in their father’s home, at Bedford Avenue and Ross Street – but a larger group would cause a disruption.

“He can come here and sit. But if he wants to come with a big group, we’ll block the door. We are in charge,” said Joel Braver, 26, adding: “Of course, he can go to the cemetery and the synagogue. He’s [the grand rabbi’s] son.”

At times, the dispute between the two factions has become physical – with punches thrown and police showing up to break up battles.

Zalman’s side has hired security guards to protect the Williamsburg headquarters, a source said.
